+Required Google APIs:
+* **Maps JavaScript API**: for the interactive maps and street views
+* **Maps Static API**: for the static map images
+* **Street View Static API**: for the backend metadata requests
+
+Required API keys:
+* **GOOGLE_MAPS_SERVER_API_KEY**: this it used by the backend and should have access to **Street View Static API**

+
+Additionally, a tile provider is also needed for map editor. This should be configured by `LEAFLET_TILESERVER_URL`, `LEAFLET_TILESERVER_SUBDOMAINS` and `LEAFLET_TILESERVER_ATTRIBUTION`. You can find some providers here: https://wiki.openstreetmap.org/wiki/Tile_servers. OpenStreetMap's tile server is fine for testing.

+
+**And you are done!** The application is ready to use and develop. In development mode an administrative user is also created by the installation script, email is **mapg@mapg.dev**, password is **123456**.
